Each episode will use the studio 'sex box', with three real couples - keen to spice up their sex life - going into the private box to have sex, before discussing what happened with Goedele in front of a studio audience.

ClearStory - the independent production company behind the programme - will also conduct an amusing and revealing national survey, while the show will give people an opportunity to open up about their bedroom hang-ups, or even indulge in first-time fantasies.

Molly Milton, co-director of ClearStory, added: "When we made the one-off episode of Sex Box, it certainly got people talking.

"Since then, we’ve been working on the format under the factual entertainment department at Channel 4 and we’re delighted to be bringing the series back with Goedele at the helm.

"As well as delivering plenty of surprises and revealing the reality of Britain’s sex lives, we’ll hear first-hand how honesty about our sex lives, our desires and fantasies is integral to relationships.”
